DETAILED DESCRIPTION

The technical solution in embodiments of the present disclosure is described clearly and completely below with reference to accompanying drawings in embodiments of the present disclosure. The embodiments described are only some embodiments of the present disclosure, and are not all of embodiments. Based on embodiments of the present disclosure, all other embodiments obtained by the skilled in the art without any creative labor are within the protection scope of the present disclosure.

The term “including” and any variations thereof in the specification and claims of the present disclosure are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus. In addition, using for terms “and/or” in the specification and the claims represents at least one of the coupled objects. For example, A and/or B represents that there are three situations including A alone, B alone, and A and B.

In embodiments of the present disclosure, the term “exemplary”, “for example” or the like is used to represent examples or illustrations. Any embodiment or design solution described as “exemplary” or “for example” in embodiments of the present disclosure should not be construed as more preferred or advantageous than other embodiments or design solutions. Specifically, using the term such as “exemplary” or “for example” is intended to present related concepts in a detailed way.

Referring to FIG. 1, FIG. 1 is a flow chart illustrating a method for processing I/O information of data according to an embodiment of the present disclosure. As illustrated in FIG. 1, the method includes the following.

At block 101, I/O information of data in a storage engine is collected by a process independent of the storage engine in a storage node.

The above process independent of the storage engine may be understood that the process and the storage engine are independent or decoupled from each other.

Collecting the I/O information of data in the storage engine may include, but not be limited to, collecting at least one of: an access mode, an access heat and a life period of the data in the storage engine.

In other words, in embodiments of the present disclosure, the I/O information of the data may include, but be not limited to at least one of: the access mode, the access heat and the life period of the data. Different I/O information may be collected based on an analysis requirement, which is not limited in embodiments of the present disclosure.

At block 102, adjustment is performed on the process in response to monitoring that a variation in usage of resource in the storage node exceeds a threshold. The adjustment is used to decrease a resource occupancy of the process.

The variation in usage of the resource may include, but be not limited to, a variation in usage of at least one of: a CPU (central processing unit), a memory, a disk I/O, a disk free space, a network card bandwidth and a system load.

When two or more resources above are included, and the variation in usage of any one resource in the two or more resources exceeds the threshold, the process may be adjusted.

Further, embodiments of the present disclosure may periodically monitor the resource in the storage node, and the variation in usage of the resource exceeding the threshold may be that a variation in usage of the resource monitored in one or more periods exceeds the threshold.

The above adjustment may be an adjustment that may reduce the resource occupation of the process, such as reducing the number of collection tasks of the process, suspending the collection. The resource occupation here may be the occupation of one or more of the CPU, the memory, the disk I/O, the disk free space, the network card bandwidth and the system load.

Through actions at block 102, a resource consumption of the process on the storage node may be controlled, thereby avoiding or reducing influence of the process on the storage engine.

As an alternative implementation, performing the adjustment on the process includes: suspending the process, and recording a breakpoint data file. The method further includes: collecting the I/O information continuously by the process based on the breakpoint data file.

The breakpoint data file may be a data file for which the process lastly completes collecting the I/O information when the process is suspended, or may be a next data file following the data file for which the process lastly completes collecting the I/O information when the process is suspended. Collecting the I/O information by the process continuously based on the breakpoint data file may include collecting the I/O information of data continuously with the next data file of the breakpoint data file as a new start point (i.e., starting from the next data file), or collecting the I/O information of data continuously with the breakpoint data file as a new start point (i.e., starting from the breakpoint data file).

In the implementation, the resource in the storage node may be sensed in real time, such that the consumption of the resource by the process may be controlled. For example, a collection task is automatically suspended during a peak period of businesses, thereby implementing precedence of the businesses of the storage engine, and the consumption of the resource may be automatically adjusted according to a system resource and the system load, to eliminate or reduce influence on the businesses of the storage engine.

Alternatively, collecting the I/O information continuously by the process based on the breakpoint data file may include: collecting the I/O information continuously by the process based on the breakpoint data file when a timer expires, in which the timer is started when the process is suspended.

In the implementation, the timer is enabled when the process is suspended. When the timer expires, the process collects the I/O information continuously. In this way, the influence on the storage engine during the peak period of the businesses may be avoided in time, and collection of the I/O information may be automatically resumed.

Description for the above implementation will be made below with reference to FIG. 2.

A resource monitoring module monitors and records usage information of the CPU, the memory, the disk I/O, the disk free space, the network card bandwidth, the system load or the like. When the variation of a certain monitoring item in one or more consecutive sampling periods exceeds the threshold, the variation is reported to a scheduling module.

The scheduling module calculates an amount of resources that need to be adjusted for the process which collects the I/O information according to the resource occupation currently received by a collection module, and sends an adjustment message to the collection module. The collection module adjusts the resources and returns an adjusted resource occupancy to the scheduling module for recording after the adjustment is completed.

The scheduling module sets a timer according to the start time. When the timer expires, a callback scheduling module sends a start command to the collection module. Then, the collection module reads a breakpoint file list, searches data to be processed, compresses and transmits the file according to its resource allocation, and then saves the breakpoint data file.

It should be noted that, all the modules illustrated in FIG. 2 are virtual modules. These modules are merely examples for illustration. An internal structure of the storage node is not limited in embodiments of the present disclosure.

At block 103, the I/O information collected by the process is sent to a target node, to enable the target node to analyze the I/O information.

The I/O information sent to the target node may be all or part of the I/O information collected by the process. The target node may be a centralized analysis node in a distributed storage system, and may be a certain storage node. When the target node is the certain storage node, the target node may perform analysis through the process independent of the storage engine.

It should be noted that, in embodiments of the present disclosure, an analysis method for the I/O information is not limited, and a corresponding analysis may be specifically performed based on an actual requirement. For example, the analysis in embodiments of the present disclosure may be: analyzing a proportion, a quantity or the like of hot data (i.e., with a high access frequency) in each storage node or the distributed storage system, may be analyzing a proportion, a quantity or the like of data for which an I/O operation is performed in sequence in each storage node or the distributed storage system, may be analyzing a proportion, a quantity or the like of data that for which an I/O operation is performed randomly in each storage node or the distributed storage system, may be analyzing a proportion, a quantity or the like of data with a shorter life period in each storage node or the distributed storage system, or may be analyzing an I/O performance or the like of each storage node or the distributed storage system. Different analysis operations may be performed based on an actual requirement.

In embodiments of the present disclosure, the process is employed to collect the I/O information and send the collected the I/O information to the target node for analysis, such that the complexity of the storage node may be reduced, a lightweight collection and analysis framework for the I/O information may be realized without bringing an extra load to the storage engine.

As an alternative implementation, sending the I/O information collected by the process to the target node includes: compressing the I/O information collected by the process into a compressed file, and sending the compressed file to the target node.

The compressed file compressed from the I/O information may be a compressed file in a compression format corresponding to the storage node. The compressed file compressed from the I/O information may be a compressed file which is compressed according to the resource allocation of the process, in which, a compression speed, a compression format or the like corresponds to the resource allocation of the process. For example, when the process is allocated with more resources, the compression is performed in a compression mode with a fast speed, or when the process is allocated the more resources, the compression is performed in a compression mode with a larger compression degree, to realize a flexible compression.

In the above implementation, a transmission overhead may be reduced and a transmission rate may be increased due to transmitting the compressed file.

It should be noted that the storage node in embodiments of the present disclosure may also be referred as a storage device, i.e., different storage nodes in the distributed storage system may be different storage devices. One storage device may also include a plurality of storage nodes, which is not limited by embodiments of the present disclosure.

In embodiments of the present disclosure, the I/O information of data in the storage engine is collected by the process independent of the storage engine in the storage node, the adjustment is performed on the process in response to monitoring that the variation in usage of the resource in the storage node exceeds the threshold, in which, the adjustment is used to decrease the resource occupancy of the process, and the I/O information collected by the process is sent to the target node, to enable the target node to analyze the I/O information. In this way, the I/O information is collected by the above process, and the collected I/O information is sent to the target node for analysis, thereby reducing the complexity of the storage node.

Referring to FIG. 3, FIG. 3 is a flow chart illustrating a method for analyzing I/O information of data according to an embodiment of the present disclosure. As illustrated in FIG. 3, the method includes the following.

At block 301, I/O information of data sent by a plurality of storage nodes is received.

It should be noted that, the method for analyzing the I/O information of data according to this embodiment may be applied to the target node in the embodiment illustrated in FIG. 1, and the I/O information of data in this embodiment may be referred to the relevant description of the embodiment illustrated in FIG. 1, which is not elaborated here.

At block 302, when the I/O information includes I/O information in different formats, the I/O information in different formats is converted into I/O information in a unified format.

The I/O information including I/O information in different formats may mean that I/O information sent by the plurality of storage nodes includes I/O information in different formats. For example, in the 10 storage nodes, 3 storage nodes send I/O information in a first format, another 3 storage nodes send I/O information in a second format, and the remaining 4 storage nodes send I/O information in a third format.

In addition, the I/O information in different formats may be I/O information in different text formats and/or I/O information in different compression formats. Further, the format of the I/O information transmitted by each storage node may also be a data format corresponding to a file storage format of the storage node.

Converting the I/O information in different formats into the I/O information in the unified format may include: converting the I/O information in different formats into I/O information in a target format. The target format may be a certain format from the above mentioned different formats of the I/O information, or may be a format other than the above mentioned different formats of the I/O information, which is not limited. Further, converting the I/O information in different formats into the I/O information in the unified format may be understood as performing normalization processing on the I/O information in different formats to obtain the I/O information in the unified format.

As an alternative implementation, when the I/O information includes the I/O information in different formats, converting the I/O information in different formats into the I/O information in the unified format includes: when the I/O information includes I/O information in a plurality of compression formats, reading the I/O information in the plurality of compression formats respectively, and converting the read I/O information into the I/O information in the unified format.

It should be noted that, the I/O information including the I/O information in the plurality of compression formats may mean that the I/O information only includes the I/O information in the plurality of compression formats, or that the I/O information includes not only the I/O information in the plurality of compression formats, but also includes the I/O information in other formats, such as the I/O information in the text format. In this case, the I/O information in the plurality of compression formats and the I/O information in other formats are converted into I/O information in the unified format.

Reading the I/O information with the plurality of compression formats respectively, and converting the read I/O information into the I/O information in the unified format may include, not decompressing I/O information in a compressed format, but performing format conversion on the I/O information in the compressed format directly during reading, thereby effectively improving performance of analysis work while reducing the disk I/O. For example, reading and converting the I/O information in the compressed format are completed in the memory, without decompressing the I/O information in the compressed format to the disk and reading the I/O information from disk for converting during the conversion, thereby reducing the disk I/O.

Taking FIG. 4 as an example, formats of the I/O information include the text format, a gz compression format, an xz compression format, a bz2 compression format and an izma compression format. The I/O information in the unified format is obtained through performing normalization processing on the I/O information in different formats, and analyzed by an analysis back end.

In an actual application, when the I/O information is analyzed, data formats corresponding to different file storage formats are inconsistent. If special treatments are performed for respective formats, a processing logic will be very complex, thereby causing a poor scalability. In this embodiment, all file storage formats may be unified into a consistent format at an analysis front end. In this way, all file formats share the analysis back end. When a new file format is added later, the new file format only needs to be converted into the unified format at the front end, thereby ensuring a good scalability.

In addition, when the compressed file is processed, the compressed file is not decompressed, but the format is directly converted during reading the compressed file, thereby effectively improving the performance of analysis work while reducing the disk I/O.

At block 303, the I/O information in the unified format is analyzed.

It should be noted that, in embodiments of the present disclosure, an analysis method for I/O information is not limited, and a corresponding analysis may be specifically performed based on an actual requirement. For example, the analysis in embodiments of the present disclosure may be: analyzing a proportion, a quantity or the like of hot data (i.e., with a high access frequency) in each storage node or the distributed storage system, may be analyzing a proportion, a quantity or the like of data for which an I/O operation is performed in sequence in each storage node or the distributed storage system, may be analyzing a proportion, a quantity or the like of data for which an I/O operation is performed randomly in each storage node or the distributed storage system, may be analyzing a proportion, a quantity or the like of data with a shorter life period in each storage node or the distributed storage system, or may be analyzing an I/O performance or the like of each storage node or the distributed storage system. Different analysis operations may be performed based on an actual requirement.

Through the actions at the above blocks, the I/O information of the plurality of storage nodes may be uniformly analyzed by one node, thereby reducing the complexity of the storage node. In addition, the method for analyzing the I/O information of data may be executed by a certain storage node in the distributed storage system, and the process for performing the analysis may be the process independent of the storage engine. In this way, no extra load is brought to the storage engine, or the method for analyzing the I/O information of data may be performed by a non-storage node.

In embodiments of the present disclosure, the I/O information of data sent by the plurality of storage nodes is received, when the I/O information includes the I/O information in different formats, the I/O information in different formats is converted into the I/O information in the unified format; and the I/O information in the unified format is analyzed. In this way, the I/O information of the plurality of storage nodes is uniformly analyzed by one node, thus the complexity of the storage node may be reduced. In addition, as the I/O information in different formats is converted into the I/O information in the unified format, analysis differentiation caused by different formats is eliminated, and it may be prevented that the compressed file is decompressed firstly and then processed, such that the scalability and performance for analyzing the I/O information are effectively improved.
